" TUB-FASTENER.

SPECIFICATION forming part of Letters Patent; No. 364,447, dated June 7, 1887.

Application filed March 15, 1886.

T0 or whom it may concern:

Be it known that I, FREDERICK A. STEG- NER, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Tub-Fasteners, of which the following is a specification.

The object of my invention is an improved fastener for securing COV(IS to tubs,firkins, boxes, and similar shipping packages.

The invention will be first fully described in connection with the accompanying drawings, and particularly referred to and pointed out in the claims.

Referring to the drawings, in which like parts are represented by similar reference-letters wherever they occur throughout the various views, Figure l is a perspective view of my improved fastener. Fig. 2 is a longitudinal central section, on an enlarged scale, taken through line w m of Fig. 1. Fig. 3 is a plan view of a device for swaging or upsetting a portion of the tack-shank against the under side of the plate and securing the tacks in place. Fig. 4 is a vertical section of the same, taken through line 1 3] of Fig. 3.

The binding-piece A is a strip of tin or other sheet metal, which has secured in its opposite ends the tacks B. These are held firmly in place by the heads of the tacks and by burrs or collars b, which are formed by upsetting a'portion of the tack-shank against the under side of the plate.

In Figs. 3 and 4 I have shown a simple device which I use as a swage-block to turn a portion of the tack shank up against the plate. In this 0 is a stationary jaw, having a shank, c, projecting back from it to be secured to a table or other suitable support, D. Pivoted to this shank is a movable or hinged jaw, E, which has a shank, e, projecting down from it and through a slot in the stationary part or shank c. The jaw E has downwardlyprojecting lugs or bosses c, which pass upon each side of the shank c, the parts being hinged together by a bolt, F, which passes through these lugs and the shank 0. Around the shank e, and between the movable jaw and shank c, is an elastic cushion of rubber, 6 the tendency of which is to throw the jaws apart when the treadle, (not show11,) which is connected to the shank e by a chain, G, or any suitable pitman, is released. The stationary and movable jaws C and E are capped Serial No. 105,288. (No model.)

with tempered-steel plates 0' and 6 These steel plates are channeled vertically, forming,

when the jaws are closed, recesses 71, to re-' hammer and forceddown into the aperture formed by the recess h, the sharp edges surrounding which turn the metal up against the plate A. The treadle is released, as in Fig. 4, thus freeing the tack. The opposite end of the plate is treated in the same way, thus completing the article.

The fastener is applied to the tub or box by driving the tack-at one end into the side of the package, then bending the plate over the edge and down upon the top, and driving the tack in the opposite end home.

For my fastener I prefer to use tin plate, because it is cheaper; but any other flexible material strong enough to hold the tack may be used. The fastener above described requires less material than those in which a portion of the plate is turned over the heads of the tacks, whether the ends of the plates are turned over the heads of the tacks or the tacks first inserted, and then the ends with the tacks in them are folded back upon the body to inclose the heads between the folded portions.

What I claim as new is- 1. As a new article of manufacture, a tubfastener consisting of a sheet-metal plate and tacks, each tack having a portion of its shank in an aperture of the plate, and its head above,

and its integral collar below, the plate, as set the top, aud'their collars b pressing the under side of said plate.
